In the figure, a block of mass m = 17 kg is released from rest on a frictionless incline of angle θ = 33∘. Below the block is a spring that can be compressed 3.8 cm by a force of 160 N. The block momentarily stops when it compresses the spring by 6.7 cm. (a) How far does the block move down the incline from its rest position to this stopping point? (b) What is the speed of the block just as it touches the spring?

A block of mass m = 4.00 kg, starting from rest, slides down a frictionless inclined plane (ramp) of length 3.00 m. The plane is inclined by an angle of θ = 25.0∘ to the ground. At the bottom of the plane, the block slides along a rough horizontal surface with a coefficient of kinetic friction μk = 0.200 until it comes to rest. Let y = 0 represent a position along this horizontal surface. a) What is the initial mechanical energy (kinetic plus potential) of the object? b) What is the speed of the block when it reaches the bottom of the ramp? c) What is the work done by the friction force? d) What is the magnitude of the friction force on the horizontal surface? e) How far does the object slide along the horizontal surface before stopping?

A block of mass m1 = 16.0 kg is connected to a block of mass m2 = 32.0 kg by a massless string that passes over a light, frictionless pulley. The 32.0−kg block is connected to a spring that has negligible mass and a force constant of k = 300 N/m as shown in the figure below. The spring is unstretched when the system is as shown in the figure, and the incline is frictionless. The 16.0−kg block is pulled a distance h = 18.0 cm down the incline of angle θ = 40.0∘ and released from rest. Find the speed of each block when the spring is again unstretched. vm1 = m/s vm2 = m/s
